32 slots on a real dedicated server. No player hosts it, so nobody gets host advantage and the game never migrates.

32-player Team Slayer on the maps you grew up on. A real dedicated server, a vote before every game, and an anti-cheat that kicks first and asks later.

Why play here
Built to run clean
You pick the map
Before each game the lobby votes from three picks, or chooses "None of the above" for a fresh ballot.
Anti-cheat enforced
Game data a normal client never sends is rejected and the sender is kicked. A ban covers their player ID, IP address and, where available, their device.
No VPNs
VPNs, proxies and hosting providers are refused, so a banned player can't just switch addresses and come back.
Ping-gated
You join only with a ping under 120 ms, which keeps fights fair. Once you're in, a lag spike never kicks you.
Always back up
The server starts on boot. A watchdog checks it every two minutes and restarts it if anything's wrong.

New to Project Reclaimer?
Halo 3 on PC, reclaimed
Project Reclaimer is a free, fan-made launcher that runs Halo 3 multiplayer from your own copy of The Master Chief Collection. It adds dedicated servers, a live server browser and lobby voting. It also brings split screen that plays online and games of up to 64 players.
Live server browser
See every community server with its map, mode, players and ping. Search by server or player name, or use Direct Connect.
No sign-up
Your profile is a nickname and a key stored on your PC. You don't need an email or password. Your player ID is under Settings → Connectivity.
Controller and split screen
Xbox and XInput controllers use Halo 3's layout. Up to four players on one PC can play together on any server.
